IMPROVEMENT IN NUT-LOCKS.

Specification forming part of Letters Patent No. 195,203, dated September 18, 1877; application iled April 11, 1877. 4

To all whom it may concern:

Be it known that I, ALLEN W. BoDELL, of Glenford, in the county of Perry and State of Ohio, have invented a new and useful Improvement in Nut-Locks, of which the following is a speciiication that will enable others skilled in the art to which my improvement relates to make and use the same, reference being had to the accompanying drawings.

My invention relates to means of preventing the screw-bolts employed to secure iishplates upon the sides of railroad-rails, at their junction, from turning and unscrewing; and it consists in the devices and combinations of devices hereinafter specically set forth and claimed.

In the drawings, Figure l is a perspective view of my invention, showing the ends ot' two rails, and the fish-joint for connecting them, with the outer or locking plate partly broken away, in order to show more fully the recess and bolt-head therein. Fig. 2 is a side elevation of the same, partly in section, through the ears or projections on the ends ot' the outer ishlplate, showing the manner of supporting the locking-bar. Fig. 3 is a transverse section therethrough on the line l l of Fig. 2. Fig. et is a similar section'on the line 2 2 of Fig. 2. Fig. 5 is a similar section on the line 3 3 of Fig. 2.

In these drawings, A indicates the rails, B the inside fish-plate, and C the outside fishplate. This outside iish-plate should have its ends turned outward in such a manner as to aord means of holding the locking bar or yoke in place. In one of these outward projections there may be a hole or socket, a', to receive a tenon or projection, a', on one end of the locking-bar, and in the other projection I form a groove to receive the other end of the locking-bar. This groove I incline on its bottom, to correspond with a like incline of the end of the locking-har, and to receive the same. Thisconstruction prevents the lockingbar from falling through the groove. I may also curve one side of the wall ot' the groove, as seen at b, Fig. 4, leaving a point, b', at the top vof the groove, where the Width of the groove should be only just sufficient to admit the end of thelocking-bar; but this curve may be dispensed with.

D indicates the locking bar or yoke, provided with transverse slots c on one side of it, of a width and in position to receive the heads ot the screw-bolts d. The inclined end of this bar is beveled or cut away at e, in order that when the bar is in position the point b', on the projection of the outside fish-plate, may be struck down to fasten it. Another means of fastening the bar in place may be a screw-bolt, as shown atf.

The tenoned end of the locking-bar isfchamfered at h, for convenience of inserting the tenon into its socket. Instead of having a tenon and socket, I might use an inclined groove at both ends like that shown at one end.

vThe practice of my invention is as follows: I first place the fish-plates in position, and insert the screw-bolts d d, of which there may be two or more, and screw them home. These bolts are only threaded on their ends to fit screw-holes in the inside fish-plate, and require no nuts. I then insert the tenon on the locking-bar into the hole a in the projection of the fish-plate, and bring the opposite end down into the groove in the other projection, the slots in the bar being slightly larger than the bolt-head to admit of this motion. I then insert the screw-bolt f, or, by a blow, strike down the point b', or both, and the permanent prevention of turning the screw-bolt is accomplished.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The outside {ish-plate C, having projections provided, respectively, with a socket and an inclined groove, substantially as specified.

2. The outside fish-plate C, having the projections provided, respectively, with a socket and inclined groove, when the groove has a curved side wall and point b', substantially as specified.

3. The locking-bar I), provided with the transverse side slots c, substantially as speciied.

4.. The locking-bar D, provided with the slots c, and having on its ends, respectively, the slots, constructed and operating together subtenon and incline, substantially as specified. stantially as specified.

5. The 1ecking-barD,provided with the slots In testimony whereof I have hereunto subc, and having on its ends, respectively, the scribed my name.

tenon and incline and bevel e, substantially as vALLEN W. BODELL.

specified. Witnesses 6. rIhe combination of the outside fish-plate F. STITH, and looking-bar, provided with transverse side BALTIS DE LONG.
